基于WebGL的三维GIS应用研究

摘要

随着网络通信、三维建模和地理信息等各项技术的进步,基于Web的三维GIS应用需求越来越广泛.本文融合了Html5、JavaScript、WebGL、MongoDB和倾斜摄影建模等技术,利用这些技术的优势,实现了基于Web的三维GIS应用,为Web三维GIS应用提供了新的实现方式,使得三维数据更具有时效性,三维数据实现跨平台浏览,用户体验更好.%With the development of network communication,3 D modeling and geographic information,the application of 3 D GIS based on Web is more and more extensive.In this paper,the integration of HtmlS,JavaScript,WebGL,MongoDB and oblique photography modeling technology,the use of the advantages of these technologies,the application of 3D GIS based on Web,provides a new way for the application of Web 3D GIS,3D data makes more timeliness,browse to achieve cross platform 3D data,user experience better.
